摘要:

Recently many particle theorists have come out in favor of asymptotic freedom instead of academic freedom, at least in the high‐energy regime. Some workers had been looking for a way to use field‐theoretic ideas to explain the scaling behavior found in deep inelastic electron‐proton scattering at SLAC. These experiments, which involve virtual photons, allow one to measure behavior at very small distances, a feature not available in normal high‐energy proton–proton scattering.

摘要:

The world's largest bubble chamber, the 15‐foot device at the National Accelerator Laboratory, was operated successfully at the end of September, and in October it ran with its 30‐kG magnet at 86&percent; of full field, using the 300‐GeV repetition rate. Earlier this year the Big European Bubble Chamber (BEBC) began operating at CERN and is now being used for physics runs; it is a 3.70‐meter device. These machines, together with the Argonne 12‐foot chamber and the Brookhaven 7‐foot chamber, may be the last generation of big bubble chambers to be built, according to Charles Peyrou, who heads the track‐chambers division at CERN and Nicholas P. Samios of Brookhaven, who has many years of bubble‐chamber experience.

摘要:

A special Topical Conference on Energy will be the outstanding feature of the 1974 joint annual meeting of the American Physical Society and the American Association of Physics Teachers. Entitled “Physics Opportunities in Energy Problems,” the Conference will present a variety of problem areas where physics might be of benefit in easing the current energy crisis.

摘要:

The discovery of many possible sources of gravitational radiation, such as neutron stars, compact x‐ray sources, rapidly rotating binary novae and the violent events occurring in quasars and galactic nuclei, has opened a new era of general‐relativity physics. In the 1960's nearly all workers in the field considered the detection of gravitational radiation “exceedingly unlikely.” From this pessimistic estimate the balance of opinion has shifted to the optimistic view that gravitational radiation, a crucial prediction of Einstein's general theory of relativity, is now within reach of current experimental techniques.

摘要:

The earth's atmosphere is always in motion, and as the winds blow over the surface of this globe, they maintain a “layer of frictional influence” or atmospheric boundary layer that extends from the surface to heights typically of the order of one kilometer. The atmosphere receives much of its heat and virtually all of its water vapor through turbulent transfer processes in the boundary layer. Furthermore, most atmospheric pollutants are released in the boundary layer, and the quality of our daily environment (we allliveinside the boundary layer!) depends strongly on the mixing capabilities of whatever turbulence happens to be around us.
